• Made for small hermit crab enclosures.

This heater suits keepers looking for an adhesive heat source for a small hermit crab enclosure, especially a plastic keeper-type cage. Its 4-watt rating, under-tank format, and stated ambient temperature increase define its intended role. It is a small-enclosure heater, not a stated solution for larger terrariums.
